` TYPOGRAPHICL COMPOSING MACHINE Filed April 5., 1940 /Nl/E/VTOR. @d ,MMM jwjwfw- Patented Nov. 26, 1940 UNITED STATES TYPOGRAPHIUAL CMPOSXNG MACHINE Paul Sckrabei, Berlin-Lubars, Germany, assigner to Mergenthaler Linotype Company, Brooklyn, N. Y., a company of New York Application April 3, 1940, Serial No. 327,682 In Germany April 3, 1939 7 Claims.

This invention relates to typographical composing machines such as are known commercially under the registered trade mark Linotype and is more particularly concerned with mechanism for adjusting the matrix line length in such machines.

Hitherto, when it has been desired to change the length of the line, it has been necessary to carry out an adjustment at four diierent places on the machine, namely, on the assembler slide, the matrix line delivery carriage, the matrix line stop on the rst elevator head and the movable vise jaw. In consequence 0f errors arising in one or more of these adjustments trouble has frequently occurred, since, if too much or insufcient space is left in the matrix line, the matrices become jammed or tilted, thereby causing the machine to be stopped.

Again, a wrong adjustment may permit metal to penetrate into the intervening spaces between the matrices or even prevent the matrices from being fully introduced into the line thereby again bringing the machine to a standstill.

It is one of the principal objects of the invention to eliminate the above disadvantages and with this and other ends in view the same cornprises a typographical composing machine of the hind referred to wherein common adjusting mechanism for the matrix line length is provided for the assembler slide` and the vise jaws and means operated from the machine are provided for returning the matrix line stop ongthe rst elevator and the long finger to their original positions.,

From another aspect the invention consists in a typographical composing machine of the said kind in which the assembler slide and vise jaws are connected by means of a member whereby common adjustment of their matrix length is carried out and wherein the controlling mechanism for such length is independent of the said member.

To carry out the said adjustment, a guide rod associated with the movable vise jaw may be extended the length of the said jaw and of the assembler slide and may be movable in the same direction as the said slide. The said rod may be provided with a fixed stop which is adapted to engage a counter-abutment of the assembler slide. In order to compensate the movement of the vise, it is preferable to divide the guide rod by a coupling which is transversely releasable but quite rigid in the direction of adjustment, so that one portion of the guide rod can partake in the movement when the vise frame is tilted downwardly, while the other portion remains in fixed guides on the machine.

In order that the invention may be more clearly understood, one form which it may assume will Ynow be described with reference to the accompanying drawing in which:

Figurel is a View of a portion of a typographical composing machine showing the assembler slide and vise jaws and the upper portion of the first elevator, the intermediate channel and the matrix delivery carriage;

Figure 2 is a section along the line A-B of Figure 1;

Figure 3 is a section along the line C-D of Figure 1;

Figure 4 is a horizontal section showing the common adjusting mechanism for the vise jaw and the assembler slide;4

Referring to the drawing:

l is the assembler slide with the assembler finger 2. The assembler is designated with 3. On the assem ler is located a small block fl having a releasing pin 5, which, through the operation of a two-arm lever 6 actuates the releasing pawl i, when the assembler ascends, whereby the long finger 8, on the left-hand side of the matrix delivery carriage is released so as to allow 4the same to strike against the line oi matrices which is now raised further upwards between the long 1inger 8 and the short finger 9 of the matrix delivery carriage. As is already known, the release of the short nger taires place when the assembler reaches its uppermost position, so as to allow the matrix line to slide towards the left through the intermediate channel it, until it reaches the rst elevator head il. In the first elevator head l I the matrix line comes up against the displaceable matrix line stop l2 and moves the latter along in front of it. The matrix line stop is formed in known manner as a longitudinally displaceable bail, which is held in its temporary position of adjustment by a brake mechanism, not illustrated in the drawing. When the rst elevator ascends into the distributing position, the matrix line stop I2 is engaged by the longitudinally movable pusher i3 and is returned thereby into its initial position by the operation of the link I4 and the lever I5 which is secured to a rock shaft |511 controlled from the cam shaft of the machine. The matrix delivery carriage is returned by means of the link i6 which is attached thereto and to the lever ll. The said lever is fixed to a rock shaft I8. The movement of the carriage to the left is brought about by means of the spring I9 bearing on the lever 2t which is secured to the rock shaft I8. The return movement through the link I6 and lever Il is controlled by means of a cam (not shown) engaging roller 22 on the arm 23 secured to the shaft I8. Upon the return of the carriage, the long left-hand iinger 8 will be restored to the original position from which it had previously been released.

The left-hand vise jaw 24 of the vise frame is adjustable to the line lengths required in the manner usual in machines of the kind under consideration. A longitudinally displaceable rack bar 25 provided with a spring controlled pawl 26 on the left hand side of the machine is used for adjusting the jaw 24, and the said pawl is releasable by means of a lever 2T. A fine adjustment of the jaw 24 relatively to the rod 25 may be carried out by means of a set screw 28.

A guide rod 29 which is adapted to extend within the reach of the assembler slide is fastened to the adjusting mechanism for the jaw 24, and is guided in guideways 30, 3|, in the same direction of movement as the assembler slide. The said guide rod 29 is subdivided into two and the parts are joined together by a cross pin 32 which at one end is secured to the left-hand part of the rod 29 and at the other end engages an aperture in the right-hand part thereof. The result of this is to ensure a coupling which is releasable in the transverse direction,` but rigid in the direction of adjustment which makes it possible for the left-hand portion of the guide rod to partake in the movement when the vise-frame is tilted downwardly, whereas the right-hand portions remains in its guideways. To facilitate its engagement, the coupling pin 32 is pointed at its free end. l

Upon the rod 29 is mounted a stationary stop 33 against which a counterabutment 34 of the assembler slide is adapted to engage. The counterabutment 34 is provided with a finely adjustable screw 35 and is located on a lever 36 rigidly connected to the assembler slide I, and which extends forwards within the reach of the guide rod 29. A downwardly rockable detent 31 is located on the stop 33, which detent, after being rocked downwardly, causes the counterabutment 34 to perform a small supplemental movement thereby allowing, as usual, the introduction of a last matrix. One end of the rod 29 is provided with scale divisions, which are employed for adjustment of the desired line length.

When it is desired to make a change in the line measure, it is only necessary to actuate the adjustable mechanism located on the left hand side of the machine, that is to say, the releasing lever 21, whereupon the common adjustment of the assembler slide and of the vise jaw may be effected by displacement of the rack bar 25, and the guide rod 29 connected thereto. At the same time the remaining positions on the machine, that is to say,- the matrix line stop I2 and the long finger 8, will be automatically adjusted to the selected line-length.

The invention is not restricted to the constructional form illustrated, inasmuch as alterations in detail may be carried out without going beyond the scope of the invention, for instance, other preferred known means of adjustment may be selected; the adjusting mechanism may also be mounted on a different part of the machine. Further, the vise jaw and the assembler slide may also be connected by separate means to a com.- mon adjusting mechanism, in which case these separate means may each contain a special ne adjusting mechanism.

Having described my invention, I declare that what I claim and desire to secure by Letters Patent is:
